The Integrin α8 chain is expressed in the glomerulus exclusively by mesangial cells and may play an important role for maintaining tissue integrity in the glomerulus during glomerular injury.

Anti-integrin therapies show potential in treating retinal diseases. Anti-integrin agents tackle the multi-factorial nature of diabetic retinopathy (DR) and AMD and show promise as injectable and topical agents in preclinical and early clinical studies. Integrin inhibition has potential to serve as Integrins are the major and best-characterized trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton during cell motility .

The data show that there are differences in the efficiency of the linkage between integrin and actin among different cell types and on the same cell type grown on different substrate densities. We identify potential Active integrin complexes recruit and activate actin nucleation machinery to produce de novo actin filaments anchored to the adhesion complex at the growing end.

Det finns ett antal undergrupper till aktin; de tre huvudgrupperna är alfa-/beta-/gamma-aktin.

Abstract α M β 2 integrin (complement receptor 3) is a major receptor for phagocytosis in macrophages. In other contexts, integrins' activities and functions are mechanically linked to actin dynamics through focal adhesions. We asked whether mechanical coupling of α M β 2 integrin to the actin cytoskeleton mediates phagocytosis. Integrin receptors connect the extracellular matrix to the actin cytoskeleton. This interaction can be viewed as a cyclical liaison, which develops again and again at new adhesion sites only to cease at sites of de‐adhesion. A number of integrin-associated proteins, including talin, parvin, filamin, α-actinin, and tensin, have actin-binding domains. However, it is not yet clear whether the primary function of these domains at the integrin junction is to bind to actin or to other proteins.

Integrins and actin are coupled through a physical linkage, which provides traction for migration. Recent studies show the importance of this linkage in regulating adhesion organization and development. Actin 2007-02-01 · The role of integrins could be just to organize preformed actin filaments into stress fibers, but they could also trigger new synthesis of actin filaments, as suggested by the recruitment of actin nucleating proteins, such as the Arp2/3 complex and formins, to sites of integrin adhesion (reviewed in ).
